Here's how I got to where I am: Install JBoss 4.2.3GA (JDK 1.6) Install Portlet 2.7.0GA Configure MySQL Fiddle settings in run.conf because JBoss was running out of PermGen space Look at user guide, then do 'mvn package' and 'cp target/Hello*war /opt/jboss/server/default/deploy/' Satisfied SimplestHelloWord is working My issue is that I don't know how to delete it. I've tried deleting the instance from the Portal tab (not the dashboard). It seems removing Simplest*war from the deploy directory does get rid of the portlet but the navigation tab is still there (but clicking on it doesn't show any output, just a blank tab) and I can't, for the life of me, work out what puts it there. I've looked through the reference guide and user guide and figure that I'm missing something really obvious but I'm not sure what.
